Redundancy alllocation is an efficient method to improve reliability and many studies on optimal redundancy allocation have been presented for various structures, such as series system, bridge system and general system by many techniques. In this paper, we deal with the problem in which redundancy or alternative component (or module) can be considered at all level in series systems. A mixed integer nonlinear programming problem is proposed and a genetic algorithm is used to find the solutions.
